The core of the pad mounted transformer’s working principle is electromagnetic induction. Pad mounted transformers are commonly used in underground distribution systems to provide stable power to residential areas, shopping malls, and factories.
In simple terms, the entire process is divided into the following steps:
1. Medium Voltage Electricity Enters the Pad Mounted Transformer
When medium voltage electricity enters the transformer via underground cables, the current flows into the primary winding. Because it is alternating current, it creates a constantly changing magnetic field in the transformer’s core.
2. The Magnetic Field Transfers Energy
This changing magnetic field is transferred through the silicon steel core to the other winding (the secondary winding). During this process, the electrical energy “jumps” across without requiring direct contact – this is the core principle of the pad mounted transformer.
3. The Voltage Is “Stepped Down.”
The voltage level is changed by relying on the turns ratio between the primary and secondary windings. In most distribution systems, the pad mounted transformer steps down medium voltage to a safe low voltage suitable for homes, appliances, and equipment. This is also an important foundation for the safe operation of power distribution panels and overall power distribution equipment.

FAQs
1. How does a pad-mounted transformer work?
It uses electromagnetic induction to step down medium voltage to low voltage. Wondon applies this in underground distribution systems.
2. What happens inside the transformer?
Current creates a magnetic field in the core, transferring energy between windings. Wondon ensures it matches your system load.
3. How is voltage actually reduced?
Through the winding turns ratio between primary and secondary sides. Wondon designs it based on project requirements.
4. Where is it usually used?
In underground power systems for residential, commercial, and industrial projects. Wondon supports these applications.
5. Can Wondon help with selection and system design?
Yes. Wondon supports full integration from selection to system design.
